Security :: One Dimensional Array With AddUsersToRoles Method
Oct 15, 2010
I've created an Excel spreadsheet for my users to upload into my web application to bulk import memberships and roles into the application. There are up to 4 different roles which users can be members of so I'm using AddUsersToRoles to add the user to one or more roles in one line of code like this:
r.AddUsersToRoles(usernames, CreateListOfRoles(Role1, Role2, Role3, Role4))
As this line of code expects a one-dimensional array of roles, I have created a function to take in the roles from my spreadsheet, add them into a one-dimensional array, and return that to the AddUsersToRoles method. The CreateListOfRoles function looks like this:
[Code]....
The error that I'm getting though is "System.InvalidCastException: At least one element in the source array could not be cast down to the destination array type." I've stepped through the Function in debug mode and all the values look correct and there are the correct number of items in the array so I don't understand what's going wrong.

First I am sorry if I am creating a thread in the wrong category as I am not sure which is the best suitable place for this question: I want to create a user defined data structure, which will be a 2 dimensional array such that each individual square of this 2-dimensional array will also store the score and the grades. ( Iam using VB.NET) More details: for example: There is an 2 dimensional array with 3 columns and 2 rows, I want to fill each of the (0,0);(0,1);(0,2) with their own score (Integer type) and grades (String Type). And this is same for the rest of the squares i.e. (1,0);(1,1);(1,2) and (2,0);(2,1);(2,2) After creating such custom data structure: "CustomArray", I should be able to create the instance of this custom data structure (which will be a class) and code something like this:
Dim objCustomArray as CustomArray
objCustomArray = New CustomArray
for i as Integer =0 to 3
objCustomArray(0,i).SetScore(1)
objCustomArray(0,i).SetGrade("Good")
Next
-------
for i as Integer =0 to 3
Dim myVal as Integer = objCustomArray(0,i).GetScore()
Dim myGrade as String = objCustomArray(0,i).gettGrade()
Next

Can we use a 2 dimensional array to bind it in our form? In my model I have this:
public class EmailDetails {
public string[] emailTo { get; set; }
public string[,] emailFieldValues { get; set; } }
So in my form to bind the emailTo is simple and this one works:
<input type="text" id="Text1" title=" " name="emailTo" maxlength="100" />
<input type="text" id="Text1" title=" " name="emailTo" maxlength="100" />
I need a 2 dimensional array so that I can match the value with something,
like this:<input type="text" id="Text1" title=" " name="EmailDetails["@name",valueofinput] maxlength="100" />

I have this array: string[,] productData = new string[5,7];
I bind it to a repeater and a call a method like: <img src="<%# getPhoto1WithReplace(Container.ItemIndex) %>"
Which is defined like:
public String getPhoto1WithReplace(Object itemIndex) {
int intItemIndex = Int32.Parse(itemIndex.ToString());
if (productData[intItemIndex, 3] != null) return this.ResolveUrl(productData[intItemIndex, 3].ToString());
else return String.Empty; }
I do not understand why it calls getPhoto1WithReplace with itemIndex as 5. My array has 5 indexes: 0,1,2,3,4, so How Container.ItemIndex can be 5?

I am getting an error when trying to serialize an object products.
Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[3,2] { {"Small","40"}, {"Medium","44"}, {"Large","50"} };
string json = JsonConvert.SerializeObject(product);//this line is throwing an error
Array was not a one-dimensional array. Is there any way to serialize a two dimensional array with Newtonsoft.json.

I want to group by the date, these values are now in a dataset. What comes up to my mind is an array list with the following: The master array would have each date listed on the dataset above, within each row of this array I would have the list of numbers for that specific date. How do I do that in VB.NET?

How do you store multi-dimensional array to viewstate? Here's what I did:
public bool[,,] regsettings = new bool[7,5,4];
bool[,,] regsettings = (bool[,,])ViewState["regsettings"]; // this line works!
regsettings[i,j,tab] = (bool)ViewState["regsettings"]; // this line no working?! The error is: Object reference not set to an instance of an object. The letters i,j, tab are just variables in the loop. They are there. I also tried: (bool[,,,]) as a cast and it is a no-go either.?

I know I can use arrayName.length to find out how many items in total in the array there are, but how can I gracefully find out how many items are in a specific dimension? I know I could probably do it in a for each loop, but it would look a little messy, does anyone know of a simple way that I may have overlooked?

My original code was in classic vb. and could use redim array to resize them. I was porting the code to c# now and lately i have run into an issue to resize a 2 dimensional array. The thing here is I have a 2 dimensional array whose 2nd dimension needs to be increased dynamically as needed to accommodate the data. For say
String[,] ary1=new String[2,10];
I'm doing some operation in a loop and filling in the data in ary1. And if the loop still continues, on reaching the ary1 upper bound i need to increase the size further to accommodate 10 more rows. I tried couple of ways to copy it to a bigger array and assign it back to the current array. but somehow dint work.

I am trying to return some data as json from an action method.
I have an employee object that looks like this:
public class Employee
{
public int EmployeeID {get; set;}
public string FirstName {get; set;}
public string LastName {get; set;}
//Other irrelevant properties
}
Then I have a view model as follows
public Class EmployeeViewModel
{
public Employee Supervisor{get; set;}
public List<EmployeeViewModel> Employees
}
I need to return a json object that looks exactly like this:
{id: 1, name: John, children: [
{id: 1, name: Joe, children: []},
{id: 1, name: Rob, children: []}
]}
For now I only need to go to the second level as above, returning and supervisor and their staff members beneath them.
How would I go about returning this in my action method(I have the viewModel object hydrated already I just need to return it as json). My problem so far has been that the children property does not get populated.

I am looping through a dataset and I would like to have the following in this array list
name, from, to, price
john, 40, 50, 39.99
mike, 20, 50, 49.99
etc.
Once I do that, or if it is possible to do it using the dataset that will work with me. But I want to do...
If john's price between from and to...
So in my code I wanted to make it easy for me and instead of memorizing the row #, I would just do.. arraylist.row("john").item("from")

I need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.

reading on the web ive found the code below; i wonder if an encrypted string using this block generates an unique result or if different encrypted sources can result in the same crypted array:
private static TripleDES CreateDES(string password)
{
MD5 md5 = new MD5CryptoServiceProvider();
TripleDES des = new TripleDESCryptoServiceProvider();
des.Key = md5.ComputeHash(Encoding.Unicode.GetBytes(password));
des.IV = new byte[des.BlockSize / 8];
return des;
}
